[The intracardiac laser irradiation of the blood in correcting left ventricular dysfunction in progressive stenocardia].

The authors studied the effect of intracardiac irradiation of blood with a low intensity Helium-Neon laser on the pumping function of left ventricle in 73 patients with progressive angina pectoris. 47 patients underwent a course of laser hemotherapy while being given medicamentous therapy, the remaining 26 received nitrates, calcium antagonists and analgesics. Employment of laser light irradiation was associated with more satisfactory clinical effect than that in patients who had not had the procedure. It has also been established that intracardiac laser light irradiation of blood makes for the improvement of the characteristics of the intracardiac haemodynamics by diminishing the volumes and augmenting the left ventricular (LV) ejection fraction. Beneficial effect of laser hemotherapy on the intracardiac haemodynamics characteristics results from the stabilizing influence the method exerts on LV regional contractility and appear to be associated with its anti-ischemic effect.
